This is the command I use to run all NUnit tests from specified library
vstest.console.exe "PATH_TO_REPOSITORY\Tests\terminalBaseTests\bin\debug\terminalBaseTests.dll" /logger:trx /TestAdapterPath:"PATH_TO_REPOSITORY"
This dll contains 27 tests but I see that they launched for some reason 3 times and the resulting message says that 81 tests were passed
Demarch provided the correct answer in the comments, for visibility and whenever other people are stumbling upon this issue I will state it here (it took me way too long to figure this out):
Symptom:
VSTest.Console.exe is running tests twice or even multiple times when NUnit, Xunit or another testrunner is used than the native one.
Cause:
The path to the TestAdapter is not correctly (to $(Build.SourcesDirectory) for example) set or not present. This is letting the runner scan all folders for test adapters. When there are multiple present, all testadapters will start a testrun causing all tests run multiple times.
Solution:
Redirect the path to the testadapter to the folder your packages are in.
If you run from the commandline set the following parameter for VSTest.Console.exe to something like this: /TestAdapterPath:"{solutionfolder}\packages"
If you run it in TFS, open the "Advanced Executions Options" section of the Visual Studio Test build step and set the following parameter to something like this: $(Build.SourcesDirectory)\packages

How can I set the path to my external binaries during test discovery in visual studio's Test Explorer? After that how to make sure, it uses the correct paths?
I use windows 10 and VS 2019. I have a solution that builds some binaries and some tests into different folders. Also, I have some 3rd party dependencies, each in its own folder.
Something like:
solutionDir/
-ownBinaries/
-testBinaries/
-externalBinaries/
I'd like to use the Test Explorer to run my tests. For this purpose, I use a .runsettings file. I installed Google Test adapter via NuGet (later it will run on CI, so this is the only option). The automatic runsetting discovery is disabled, and this file is selected as the runsettings file. It overrides the workingDir to my ownBinaries folder, and extend the PATH enviroment variable with the externalBinaries. The relevant parts are:
<SolutionSettings>
<Settings>
<AdditionalTestExecutionParam>-testdirectory=$(SolutionDir)</AdditionalTestExecutionParam>
<WorkingDir>$(SolutionDir)ownBinaries</WorkingDir>
<PathExtension>$(SolutionDir)externalBinaries</PathExtension>
</Settings>
</SolutionSettings>
This is works fine, after my tests are discovered, but I have problems when it tries to discover my tests.
I use google test and c++, so the test discovery tries to run those tests with the --gtest-list-tests argument, then populate the view with the test name, case, etc. The binaries are just fine, builds without error, I can run them from the debugger, and they produce the output I want.
But the test explorer won't show them, because it doesn't set the externalBinaries path.
This is what lead me to this situation.
First I copied every binaries next to my test exe, namely into the testBinaries folder. Then, I could run it in the cmd with the --gtest-list-tests argument. Everything was fine, all my test names showed up. Started VS, and Test Explorer discovered all my tests, it was able to run them.
Then I done a clean build, so the external stuff deleted from the testBin folder. The Test Explorer cached the test names, so it was able to run them.
Restart VS. Test Explorer tries to discover my tests. but it fails whit this helping message: (removed date+time)
Google Test Adapter: Test discovery starting...
Failed to run test executable 'D:\MySolution\testBinaries\SBCUnitTest.exe': One or more errors occurred.
Check out Google Test Adapter's trouble shooting section at https://github.com/csoltenborn/GoogleTestAdapter#trouble_shooting
In particular: launch command prompt, change into directory '..\ownBinaries', and execute the following command to make sure your tests can be run in general.
D:\MySolution\testBinaries\SBCUnitTest.exe --gtest_list_tests -testdirectory=
Found 0 tests in executable D:\MySolution\testBinaries\SBCUnitTest.exe
Test discovery completed, overall duration: 00:00:00.3022924
Have you noticed that -testDirectory= is empty despite it is set in the runsettings file?
I'm completely lost how I can proceed with it. This workaround is quite heavy to copy all files, then delete all but the test binaries each time when I start VS.
Here is the link for the Troubleshooting section mentioned in the error message.
I've read through the readme file on github, also the runsetting docs on Microsoft's website.
Edit
I made progress with the VsTest.console.exe, I can successfully run all my tests with the proper arguments as below:
& "VSTest.console.exe" *_uTest.exe /Settings:..\MySolution.gta.runsettings /TestAdapterPath:"..\packages\GoogleTestAdapter.0.18.0\build\_common\"
I use the same *.runsettings and *.gta_settings_helper files. Those files are used to get absolute paths for the dependencies. I could run this from different folders, but then I had to adjust the arguments (test discovery pattern, relative path to runsettings, and relative path to GTA).
Great news, that it successfully runs on Azure (it uses vstest.console).
Edit 2
Tried to merge the workingDir and pathExtension nodes, so only one needed (the pathExtension). No success.
Tried to install Test adapter for google test in the VS installer, delete the runsetting file, and set the properties in VS->Tools->Options then Test adapter for google test. Even the example pathExtension didn't worked for me.
Found the extended logs under %AppData%/Local/Temp/TestAdapter/someNumber/*.txt and in that log I've found one line as the runsettings file. I paste here the formatted version of the log
<RunSettings>
<GoogleTestAdapterSettings>
<SolutionSettings>
<Settings>
<WorkingDir>$(SolutionDir)</WorkingDir>
<PathExtension>$(SolutionDir)externalBinaries</PathExtension>
</Settings>
</SolutionSettings>
<ProjectSettings>
</ProjectSettings>
<GoogleTestAdapterSettings>
<SolutionSettings>
<Settings>
</Settings>
</SolutionSettings>
<ProjectSettings>
</ProjectSettings>
</GoogleTestAdapterSettings>
</GoogleTestAdapterSettings>
</RunSettings>
Does anybody know why is there an empty google test adapter setting? Where does it comes from? I think this is overwrites my settings.
It turned out, before first run the relative paths are not known.
Trivial solution
Add the full path to the PATH Extension under Visual Studio -> Options -> Test Adapter for Google Test settings. Meanwhile the custom *.runsetting file is not selected.
Using this method all my tests are discoverable, but it is a manual setting for each repo cloned.
I have this build :
It works fine. The only issue is that the Test Results are overridden. So I actually end up with the test results for the last test project executed.
This is executed by build engine;
C:\Program Files\dotnet\dotnet.exe test C:/agent/_work/4/s/test/Services.UnitTests/project.json --configuration release -xml ./TEST-tle.xml
C:\Program Files\dotnet\dotnet.exe test C:/agent/_work/4/s/test/Web.UnitTests/project.json --configuration release -xml ./TEST-tle.xml
What could help:
1) having "dotnet test" generate XML output file - did not find a way how to do that
2) Use a variable for -xml output file in Build Task. That variable could be a random string/number or just a project name being tested - like what Build engine feeds to "dotnet.exe test". No way how to do that.
Any ideas? Thanks.
I think that, although you're running the task against all of the projects in one go, as the .Net Core (Preview) task doesn't have a working directory, that the test results are being generated at solution root (or similar) and done for each project in turn.
I set mine up using simple command line tasks...
Tool: dotnet
Arguments: test -xml testresults.xml
Working folder: {insert the folder for the project to test here}
These work fine but I have one set up for each project. You could try creating a task for each library and adding the full path to the test results argument (or name them appropriately as starain suggested).
This feels like a minor bug to me.
Based on my test, it doesn’t recognize the date variable as Build Number.
To deal with this issue, you can add another .Net Core (Test) step to run xunit test with different result file.
For example:
I have created a TFS2013 Build Definition using the template TfvcTemplate.12.xaml
I have specified a test run using VSTestRunner and enabled code coverage.
I am integrating this build with sonar analysis by specifying pre-build and post-test execution script.
Prebuild script arguments: begin /name:PrjName /key:PrjKey /version:1.0 /d:sonar.cs.vstest.reportsPaths="tst*.trx"
I have the "Unit Test Coverage" widget on my sonar dashboard.
It shows Unit Test Coverage %
However, it does not show the unit tests (ie how many tests were run, how many failed ,etc).
I looked in the build output. There is a "tst" folder, however it is empty.
I cannot find the trx files.
I believe that either the trx files are not properly generated or
I am not setting the "sonar.cs.vstest.reportsPaths" correctly.
Please help !!
Relative paths are not well supported: Specify an absolute path wildcard to your *.trx reports. See https://jira.sonarsource.com/browse/SONARMSBRU-100 for details on the bug.
Note that you probably can use the TFS 2013 environment variables to construct this absolute path wildcard: https://msdn.microsoft.com/en-us/library/hh850448.aspx#env_vars
As part of the TFS Build we execute tests that generate trx files. I would like to execute on these set of files code coverage analysis using OpenCover, without re-executing the Unit Tests.
Is there a way to do so?
Thanks
This is a little command-line & duck-tape but it gets the OpenCover and Test results in 1 pass, and publishes test results and coverage to TFS or Visual Studio Team Services (previously VSO).
Create .bat file Run-Tests.bat that calls vstest.console.exe to test your code with the /logger:Trx option
This creates a .trx file that can be published to TFS
Run the tests
OpenCover.Console.exe -target:"Run-Tests.bat" -output:"OpenCover.xml"
Run OpenCoverToCoberturaConverter:
OpenCoverToCoberturaConverter.exe -input:OpenCover.xml -output:Cobertura.xml
Publish the test results and coverage to TFS:
Unfortunately not - OpenCover needs to instrument your code as it runs in order to determine which bits of code were executed.
I have an error similar to the one in this post. Now, I'm sure I've made some stupid error somewhere, probably related to releasing an object or an observer or what-not, but since I can't seem to find a way to debug the code I thought I could use the NSDebugEnabled, NSZombieEnabled and MallocStackLogging (as shown here).
Can it be done using OCUnit? If so, how? I just can't find an "executable" to set these parameters on...
Thanks!
Aviad.
Unfortunately, Dave's solution didn't work - I kept getting errors and mistakes. I eventually got GHUnit to work on my project, found the problem by debugging, but it had its own problems so I now use both it and OCUnit which is slightly better integrated in terms of showing the results in the results tab.
sigh. When will we get to see a good, complete unit testing framework for Obj-C?
This may have been fixed in recent Xcodes, but I get zombies by doing
Go into schemes (cmd <)
Open Test, then Arguments tab
Uncheck "Use the Run action's arguments and environment variables"
"+" an environment variable "NSZombieEnabled" = "YES"
Well, NSZombieEnabled and friends are environment variables, which means they have to be run on an executable. The default setup for a unit testing bundle is for the tests to be run during the build process, and not during execution.
So the way to fix this is to make it so that your tests don't run during the build phase, but instead run them as part of an executable.
Here's how I do that:
Inside your Unit Test bundle target, remove the "Run Script" build phase. It's that step that executes the tests after compiling them.
From the Project menu, choose "New Custom Executable..." and name it something meaningful, like "otest"
Make the executable path to be the otest binary, which should be located at /Developer/Tools/otest
Set the following environment variables on the otest executable:
DYLD_FRAMEWORK_PATH => {UnitTest.bundle}/Contents/Frameworks
DYLD_LIBRARY_PATH => {UnitTest.bundle}/Contents/Frameworks
Set the following program arguments on the otest executable:
-SenTest All (this will run all of the unit tests)
{UnitTest.bundle}
You can now select your unit test bundle as the active target, and the otest executable as the active executable, and then build and debug. This will let you set breakpoints, set other environment variables (like NSZombieEnabled), and so on.
If you only want to debug a certain suite or specific unit test, you can change the -SenTest All argument to -SenTest MyUnitTestSuite or -SenTest MyUnitTestSuite/myUnitTestMethod.
It took me quite some time but I finally managed to make it work for my project.
To create the "logic" tests I followed Apple guidelines on creating logic tests.
This works fine once you understand that the logic tests are run during build.
To be able to debug those tests it is required to create a custom executable that will call those tests. The article by Sean Miceli on the Grokking Cocoa blog provides all the information to do this. Following it however did not yield immediate success and needed some tweaking.
I will go over the main steps presented in Sean's tutorial providing some "for dummies" outline which took me some time to figure out:
Setup a target that contains the unit tests but DOES NOT run them
Setup the otest executable to run the tests
Setup the otest environment variables so that otest can find your unit tests
Step 1 - Setting up the target
Duplicate your unit tests target located under your project Targets. This will also create a duplicate of your unit tests product (.octest file). In the figure below "UnitTest" is the original target.
Rename both the unit tests target and the unit tests product (.octest file) to the same name. In the figure below "UnitTestsDebug" is the duplicate target.
Delete the RunScript phase of the new target
The name of both can be anything but I would avoid spaces.
Step 2 - Setting up otest
The most important point here is to get the correct otest, i.e. the one for your current iOS and not the default Mac version. This is well described in Sean's tutorial. Here are a few more details which helped me setting things right:
Go Project->New Custom Executable. This will pop open a window prompting you to enter an Executable Name and an Executable Path.
Type anything you wish for the name.
Copy paste the path to your iOS otest executable. In my case this was /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/Developer/usr/bin/otest
Press enter. This will bring you to the configuration page of your executable.
The only thing to change at this point is to select "Path Type: Relative to current SDK". Do not type in the path, this was done at step 3.
Step 3 - Setting up the otest arguments and environment variables
The otest arguments are straightforward to setup... But this proved to be my biggest problem. I initially had named my logic test target "LogicTests Debug". With this name and "LogicTests Debug.octest" (with quotes) as argument to otest I kept having otest terminating with exit code 1 and NEVER stopping into my code...
The solution: no space in your target name!
The arguments to otest are:
-SenTest Self (or All or a test name - type man otest in terminal to get the list)
{LogicTestsDebug}.octest - Where {LogicTestsDebug} needs to be replaced by your logic test bundle name.
Here is the list of environment variables for copy/pasting:
DYLD_ROOT_PATH: $SDKROOT
DYLD_FRAMEWORK_PATH: "${BUILD_PRODUCTS_DIR}: ${SDK_ROOT}:${DYLD_FRAMEWORK_PATH}"
IPHONE_SIMULATOR_ROOT: $SDKROOT
CFFIXED_USER_HOME: "${HOME}/Library/Application Support/iPhone Simulator/User"
DYLD_LIBRARY_PATH: ${BUILD_PRODUCTS_DIR}:${DYLD_LIBRARY_PATH}
DYLD_NEW_LOCAL_SHARED_REGIONS: YES
DYLD_NO_FIX_PREBINDING: YES
Note that I also tried the DYLD_FORCE_FLAT_NAMESPACE but this simply made otest crash.
Step 4 - Running your otest executable
To run your otest executable and start debugging your tests you need to:
Set your active target to your unit test target (LogicTestsDebug in my case)
Set your active executable to your otest executable
You can build and run your executable and debug your tests with breakpoints.
As a side note if you are having problems running your otest executable it can be related to:
Faulty path. I had lots of problem initially because I was pointing to the mac otest. I kept crashing on launch with termination code 6.
Faulty arguments. Until I removed the space from bundle (.octest) name I kept having otest crash with exit code 1.
Wrong path in environment variables. [Sean tutorial][8] has lots of follow-up questions giving some insight on what other people tried. The set I have now seems to work so I suggest you start with this.
You may get some message in the console which might lead you to think something is wrong with your environment variables. You may notice a message regarding CFPreferences. This message is not preventing the tests from running properly so don't focus on it f you have problems running otest.
Last once everything is working you will be able to stop at breakpoints in your tests.
One last thing...
I've read on many blogs that the main limitation of the integrated XCode SenTestKit is that tests cannot be run while building the application. Well as it turns out this is in fact quite easy to manage. You simply need to add your Logic tests bundle as a dependency to your application project. This will make sure your logic tests bundle is built, i.e. all tests are run, before your application is built.
To do this you can drag and drop your logic test bundle onto your application target.
